Title: Indicating equipment for decimal equivalents of binary numbers
IPC: H03M7/08
Filed: 1958-06-16
Abstract: 832,670. Binary to decimal code converters. STANDARD TELEPHONES & CABLES Ltd. (Lorenz A.G., C.). June 16, 1958, No. 19173/58. Class 40 (1). An optical - indicating device adapted to convert binary values into their decimal equivalent has a number of slotted discs (such as the two shown in Fig. 3) having zones, each zone having a slot and a tooth arranged in either order, and the discs are each rotatable through a slot's width to two alternative positions, representing input binary values " 1" and "0" respectively, the arrangement being such that a passage through aligned slots appears in a position corresponding to the decimal equivalent. In the simple example of Fig. 3, the two discs are slotted as shown. In the first case a where both discs are in the " 0 " position there is a through passage in the " 0 " decimal position. In case b the top disc is in the " 1 " position and a through passage appears in the " 1 " decimal position. In case c the top disc is in the " 0 " position and the lower is in the " 1 " position so that a passage appears at decimal position " 2." In case d both discs are in the " 1 " position and the passage is in the decimal 3 position. The arrangement of slots and teeth may be in accordance with the plain binary code, as in this case, or with the cyclic permuting code. Fig. 2 shows a conversion arrangement for eight digit binary numbers, there being eight discs each movable to the left to assume the " 1 " position. A through passage appears at the corresponding decimal digit for example if the first and fourth disc are moved in slot's width to the left in response to the binary,number 00001001 a passage is made in the 9 position. As shown in Fig. 4, the discs are rotated to their " 1" positions by electromagnets acting on arms 3. Lamp 4 cooperates with a reflector to project light through the passage made by aligned slots in the discs. A scale 10 on the front bears corresponding decimal numbers.

Abstract: 779,358. Abrasive sheets. BAY STATE ABRASIVE PRODUCTS CO. June 30, 1954 [July 2, 1953], No. 19218/54. Class 60 [Also in Group VIII] An abrasive sheet comprises a base of open mesh fabric 11 woven from continuous filament yarns 12, 13 which are impregnated and/or coated with a flexible material, and a coating 19 of abrasive granules deposited over the entire exposed surfaces of the yarns and held thereon by a hardened adhesive. The fabric may be a plain, twill gauze or leno weave of rayon, nylon or glass single or mutlifilament yarns, and may have double warp yarns. The yarns may be impregnated before weaving, or the fabric may be impregnated after weaving sufficientimpregnant being preferably used to provide a coating on the surfaces of the yarns with Consequent cementing at their intersections to prevent yarn slip. Suitable im-. pregnants are synthetic rubber latices, e.g. neoprene, butadiene-acrylonitrile copolymer, or polyvinyl resin latices, or solutions or emulsions of polyvinyl butyral, polyvinyl acetate, or ethyl cellulose. The adhesive for the abrasive may liquid ' A ' stage phenolic resins, oil modified phenolic resins, oleo resin varnishes, or urea-formaldehyde resins. The abrasive may be silicon carbide or alumina, and it is preferred to use irregular aggregates thereof, cemented by the same adhesive as that used to bond them to the fabric, to produce thick abrasive coatings, which reduce the fabric mesh openings by 15-40 per cent. The impregnated base fabric 11 is fed from roll 21, through adhesive tank 23 and squeeze rolls 29, past rotating brush 31, which breaks films of adhesive across the fabric meshes.

Title: Improvements in or relating to drives
Inventor: TAUSCHEK MAX JOSEPH
IPC: F01P7/04
Filed: 1960-05-31
Abstract: 914,580. Cooling cylinders. THOMPSON RAMO WOOLDRIDGE. May 31, 1960, No. 19251/60. Class 7(2) [Also in Groups XXVI and XXIX] An hydraulic coupling 1, Fig. 1, for the fan 3 of an internal combustion engine 2 comprises a driving element 18, Fig. 2, and a driven element 20 separated by a coupling space of constant volume, and a temperature-responsive expansible and contractible means for displacing fluid into and out of the coupling space. The drive may be transmitted hydrodynamically or, as described, by the viscosity of the fluid. The driving element 18 forms an end wall of a housing 28 which is mounted on a sleeve 10 driven by a belt 68 from the engine 2 and has a wall 32 secured by a bellows 30 to its other end wall 24 in contact with the air or water cooling system of the engine. The heat may be transmitted by conduction or radiation; in the latter case, the wall 24 is preferably painted flat black. The bellows contains a bi-metal element or a fluid, such as gas or alcohol in liquid 36 and vapour 38 form, responsive to temperature so that, when heated, it expands to displace a viscous liquid 26 formed into a ring by the centrifugal effect of rotation of the housing into the coupling space between the wall 18 and the driven element consisting of a disc 20 secured to a shaft 14 to transmit torque to the fan. Depending on the quantities of fluid in the housing and bellows, an increase in centrifugal force caused by increased rotation of the housing may compress or expand the bellows to vary the quantity of fluid in the coupling space. The movement of the bellows may be effected against spring, atmospheric or gaseous pressure. In another embodiment, the driving element consists of a disc 142, Fig. 6, keyed to a shaft 126 which is belt-driven from the engine and supports a housing 144 carrying the fan 103; the disc may have free or fixed axial connection to the shaft. The disc extends into a coupling space between surfaces 166, 167 on the housing which is formed with a recess 160 receiving an annular, radiallyextending chamber 162 of brass or plastic material containing a temperature responsive fluid such as acetate, alcohol or the fluid known under the Registered Trade Mark "Freon". Expansion or contraction of the chamber controls the amount of fluid, such as silicone or petroleum oil, between the surfaces 166, 167 and hence the torque transmitted by the coupling. The housing is shaped to form a space 168 and centrifugal force acting on the fluid in the space, between the surfaces 166, 167 and in the recess 160, acts on the chamber 162 to vary its volume and the amount of liquid between the surfaces. In a further embodiment, the annular chamber 162 extends axially of the coupling to reduce the effect of centrifugal force. Cooling fins 178, 180, 182 are provided on the housing.

Title: Tubular filaments
Inventor: SPEAKMAN RAYMOND HOLDEN
IPC: D01D5/24
Filed: 1961-05-29
Abstract: 950,213. Tubular filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 23, 1962 [May 29, 1961], No. 19264/61. Heading B5B. Tubular filaments are made by melt-spinning fibre-forming synthetic linear polymers in the form of a thin-walled tube, e.g. through an annular orifice, and introducing a gas supply into the tube, the annulus dimensions and the rate of introduction of the gas being so related to the wind-up speed and final desired diameter of the filament that the wall thickness does not exceed 8 microns, and is preferably less than 5 microns. Preferably during melt-spinning the gas contained within any finite section or portion of the tube is of substantially the same volume as that contained within any other section or portion of the tube of the same total weight as the said first section, due allowance being made for variation of temperature and further expansion of the gas during the process. Gas may be introduced at such a rate that after solidification no inflation of the tube to a diameter greater than that of the annular spinneret aperture takes place, but sufficient to prevent undue contraction of the tube. The tube may be collapsed by pulling it through a narrow shaped guide, nip, or die, perforated or slit, and oriented by winding at high speeds using fluid, liquid or mechanical drag forces, especially by drawing between feed rolls and draw rolls.- The final denier of the filaments is preferably 25-150. Specified materials include nylon, polyesters and copolyesters based on terephthalic acid, especially polyethylene terephthalate, and stereospecific polypropylene. Optimal spinning conditions may be ascertained from a formula given in the Specification.

Title: Improvements in or relating to the extraction of copper and other metals
IPC: C22B7/00
Filed: 1946-06-27
Abstract: Copper is separated from an alloy containing copper, nickel, zinc and possibly other metals by extracting with a cuprammonium solution, treating the extract with carbon dioxide, and evaporating ammonia from the solution to precipitate copper in cuprous form with or without a proportion of other metals as oxides, carbonates, or basic carbonates.  An alkali metal salt, e.g. Na2CO3, is preferably added before evaporation of ammonia to improve the separation.  The copper precipitate if pure may be treated with sulphuric or other strong acid to form a cupric solution and copper powder.  If contaminated with nickel and zinc the copper precipitate may be heated with a cupric salt solution when nickel and zinc are replaced by copper. The treated precipitate containing cupric and cuprous oxide is treated with a solution of ammonia and carbon dioxide forming cuprammonium solution for reuse and a cuprous oxide precipitate which may be dried to red Cu2O or treated with acids to yield a precipitate of copper powder and a cupric solution for reuse.  The cupric leach liquor containing nickel and zinc may be treated with a zinc/nickel precipitate, obtained by evaporating the original solution, yielding in suitable conditions a zinc precipitate and a nearly pure nickel solution.  The copper powder may be dried with a water-miscible organic solvent, e.g. alcohol or acetone. Ammonia and carbon dioxide evolved at various stages may be recovered for reuse.ALSO:Copper is separated from an alloy containing copper nickel, zinc and possibly other metals by extracting with a cuprammonium solution, treating the extract with carbon dioxide, and evaporating ammonia from the solution to precipitate copper in cuprous form with or without a proportion of other metals as oxides, carbonates, or basic carbonates.

Title: Improvements in and relating to the manufacture of alginate threads
IPC: D01F9/04
Filed: 1947-07-22
Abstract: A continuous spinning process for the production of alginate threads comprises projecting an aqueous alkali alginate solution having a pH of less than 9.5 into a neutral bath made up from an alkaline earth metal salt and water substantially free from temporary hardness, passing the thread thus formed to a series of thread-advancing devices for subsequent treatment, including washing and drying, and, prior to drying, treating the thread with a cation-active compound. The neutral bath is defined as one of pH range of the order of 5 to 8.5.  It should contain no mineral or organic acid other than the very small quantity of carbon dioxide normally dissolved in aqueous solutions, and no carbonates or hydroxides other than a small quantity of dissolved calcium carbonate not exceeding 5 parts per 100,000 by weight.  The washing of the formed thread is preferably carried out with demineralised water, i.e. water containing less than 8 parts of total solids and less than 1 part of calcium salts per 100,000 parts by weight.  The cation-active compound, e.g. cetyl pyridinium bromide may be added to the spinning solution or the washing bath, but is preferably applied after the washing, e.g. by passing the thread over a wick on to which a solution of the compound is dropped so that the thread takes up about 2 per cent of the compound based on the weight of the dried thread.  The thread-advancing devices may be of the kind in which the thread is advanced axially along the device while travelling helically.
